There's Sweetie Pie, which Perry describes as "sweet and subtle, but with just the right amount of volume", or Oh Honey for that "vintage flick at the corners".
Then there's the double lashes, Oh, My for a "full texture" but Katy says her favourite style is Cool Kitty - "a perfect evening wear lash... it can add the ideal finishing touch for a smoky look".
Each set is available for a reasonable £5.95 at Boots and Superdrug stores nationwide from February.
